01 4x4 looking at sxe 62/68/12 dap 150s quad adren. current fass 150,4in ex, built auto tripple disc low stall conv,billet input 354 rear 285 tires

i would like to thank everyone for the advice ,really helpful group, again tks to everyone.

sac or voc dislike smoke, reliabilty is issue at this level a few more hp not that important

injector recomendations, and would they work for a while until i can get quad

it is smokey on all settings just less on lower settings , yes boost leaks check ok, it is a low stall converter,which would be best solution injectors , tuner, smaller turbo this is new turbo replaces a afe bladerunner which had crazy high drive pressure, guess i went overboard the other way

sorry i started this in intro section, i need advice , truck is 01 cummins 4x4 extended cab, current mods are edge juice 4in exhaust afe intake horn, fass 150 built trans billet input shaft tripple disc converter,borgwarner 62/68/12sxe turbo, it has either rv 275 or 75 hp injectors. truck is very smoky with any pedal input under 1700 rpm,could i get some advice please

240,000miles everythingis good ,did boost leak test, holds 25lb new bhaf, fass,18lb idle 14lb wot. this is new turbo which do i need most larger injectors better tuner, smaller turbo?
